' BEAM-HANGER CABLE EYE.

Application filed April 14, 1926. Serial No. 102,089.

a; of pump hanger cables to their rod grips.

It has long been thepractice to utilize a bridle cable whose ends areinserted in a socket and held by Babbitt metal poured into the socket tofill the interstices to bind the cable end in the socket so that whenthe eye of the socket is slipped onto a pin on the rod grip the cablecannot pull out.

The custom is to send the sockets to the customer and he babbitts in thecable ends. It will be seen that this requires use of a firev somewherearound the site commonly at the derrick shop of an oil well where thereis .much inflammable material, and often there is natural gas leakingfrom the well.

The broad object of -my present invention is to provide means which willelimina e both the babbitting in and the melting out of the cable endsand, so, materially reduce the hazard of fire from such a source ofdanger.

Another object is to provide a device which, while being effective tofirmly connect the cable to a desired part, as a rod grip, will permitof ready releaseand reattachment, or replacement, of the cable as may berequired for several purposes or reasons; as to change length or size ofthe cable.

Another object is to provide a device combining a two-part cable-eyeincluding a clamp feature so operative, when set, that the cable-eye isbodily reversible, on a pin, side for side and efiects a center line ofpull axially of the cable and medial plane of the eye-ring-body.

A further object is to provide a device which will securely grip uponcables of different diameters; will provide clearance for the usualstrand-wrapping which is used to prevent unstranding; will not sharplyangle or pinch the cable extending from the fasteuing; and will so kinkthe cable tail as to provide a safety feature against slipping.

Other objects and advantages will be made manifest in the followingspecification of apparatus embodying the invention, it being understoodthat modifications, variations and adaptations may be resorted to withinthe spirit of the invention and its scope as here claimed.

Figure 1 is a perspective of the applied invention. 7

Figure 2 is a top plan of the device.

Figure 3 is a perspective of the clamp eye.

Figure at is a longitudinal section showing a cable in place. v

, Some types of polish rod grips are provided with laterally project ngpins onto which are slipped the eyes of elongated sockets (as in myPatent #1,482,148.)

In such sockets the ends of a beam hanger cable is usually held by afilling of Babbitt metal. The operations of embedding and melting outthe soft metal are obvious and the necessary fire is a hazard to beassidu ously avoided around oil and gas fields.

In my present invention I aim to provide a beam hanger, cable eyewholly'devoid ot the babbitting feature, and possessing numerousadvantages over such forms of sockeis and eyes as will now appear. v I

The presentcable eye includes a main body part 2 having an elongatedconcaved seat 3 the lower end of which is angularly deflected at 4 tothrow a substantial bend or kink in the tail end of the applied wirerope when it is clinched in place under a gripping plate 10. One end ofthe body 2 is provided with a stout ring or eye part 5 the plane ofwhich is slightly ofi'set as to the general plane of the body 2 so as tobring the medial plai'ie of the eye-part in alinement with the axis ofthe average cable 0 utilized in the device.

It is to be observed that the far ends of the plate and the body areprovided with outturned lips 17 which permit the cable to take a gradualturn without a sharp pinching corner action, when the cable sways as tothe clamping parts 210. The plate is interchangeable and is reversibleendwise for application to the rope, each end having a lip 17. The shortplate provides, with seat part t, a mouth for the outwardly deflectedcable tail C which is usually wrapped at 18 to prevent unstranding. Thewrapping clears the mouth and is not gripped by the parts, whose seats,obviously, are less, each, than 180 degrees angular length, as to therope center so as to reliably clinch on any proper size of rope (cable).

The applied cable is subjected to a four point centering grip efiect forthe full length of the seats 3-11. V

(ill

Ease of attachment and detachment, and light Weight are achievedadvantages.

Since fire destruction of oil, Well platforms, shop-houses and derricksis no in frequent event the danger of dropping the load of parts bymelting of the usual babbitt socket of the cable is Wholly eliminated bymy present clamp and eye means.

In Figure 3 the movable clamp plate 10 is hinged at 1O on one side ofthe body 2. One bolt"? serves to grip the cable in the clamp parts.

What is claimed is:

1. In a beam hanger, a bridle cable gripping means including a body parthaving 7 on its cable axis a pin receiving eye-part lit Whose axis istransverse to the length of the body part, and means hinged on the bodyfor detachably clamping .a cable end along the said part, said meansincluding a single efiective setting bolt, the pivot ax s of the hingemeans being parallel to one side of the cable lying axially on the bodypart.

2. In a beam hanger, a bridle cable gripping means including a body parthaving a pin receiving eye-ring Whose axis is transverse to the lengthof the body part, and means hinged on the body part for detachablyclamping a cable end along the body part; said eye-ring being bodilyoffset a.

to the plane of the body so as to bring the medial plane of the ring inline of the axis of the applied cable end said means including a pivotpin disposed on the body and parallel to the cable axis.

3. In a beam hanger, a cable gripping leans including a body part havingon its cable axis a pin receiving eye-ring Whose axis 'is transverse tothe length of the body part, said part having a concaved cable seatalong one face, and a movable clamping plate having a complementaryclamping seat to set against the cable in the body seat, and singlebolt-clamp means for fastening the plate and said body onto the cableand an elongated hinge pin'and journals therefor along one side of thebody and the plate; the pin lying parallel to the cable seats.

4. In a beam hanger, a cable gripping device including a body parthaving an eye portion with the axis of the eye transverse to the lengthof the body portion, a clamping plate terminating short of the eye porton, and hingedly connected to one side of the body on an axis parallelto an applied cable said eye portion having its ring bodily ottset intoa position partly under the said plate so as to approximately aline witha cable gripped in said parts.
